Well shit, I just discovered that Munsey's (a website with a massive collection of pulp fiction available for free) has been offline for a good long while (2 years?)
Along with every other website I was using for Public Domain pulp fiction.
Apparently they got taken down for not being super strenuous with their copyright policy.
Aside from Project Gutenberg, what's out there? I want stuff from the 30s that didn't get it's copyright renewed (like The Spider Strikes)
